Pattaya's Underwater World is a place you simply must visit during your vacation to Thailand. It is where you can see a mesmerising array of marine creatures up and close, and even interact with some of them! Located within driving distance from Avani Pattaya Resort, you can walk through a series of exhibits including the Open Ocean Zone, Coral Reef Zone, and even something called the Giant of Siam Zone! Between 10:30 and 11:30 in the morning, you would even be able to witness the feeding sessions at each of these zones – if you miss it, there is always the afternoon session!
